This is a great hotel but they have been raising the rates through the roof lately (and I'm not sure the new prices are worth it)! I love how gorgeous everything is - the decorations are impeccable - but I was able to stay in a corner suite at the Aria next door for less than a standard room at the Cosmopolitan my last trip. Needless to say, given the choice, I'd stay in the corner suite every time.
But the Cosmopolitan staff is super friendly and even if you don't stay here, I'd definitely recommend walking through (especially if you are with a bachelorette party - all those sparkles!). I love the chandeliers and casino. They also have great restaurants and a very cool pool. Hopefully they will stop price gouging and I can stay there again.
